Disclosed herein is a machine comprising a sweetened paste kneading device that supplies an extrusion group constituted by two telescopically coupled, vertical tubular blocks, namely a first fixed tubular block and a second movable tubular block closed at the bottom by an extrusion plate which, with the said tubular blocks, defines a variable volume chamber; and a conveyor that supplies baking tins in succession to the overhead said extrusion group. When the variable volume chamber is full of paste, "piped" or "poured in" biscuits are created with, in the first instance, the volume of the said chamber maintained constant and, in the latter, firstly a decrease and then a volumetric increase. When the paste is "piped", the separation from the said extrusion plate of the ropes of extruded paste is achieved with the use of cutting means, while for "poured in" paste, it occurs through breakage caused by the decompression of the paste in the said chamber. When no paste is in the chamber, "poured in" biscuits are created through, in this order, a reduction in the volume of the chamber, the operation of the kneading device, with the consequent extrusion of the paste, and then an increase in the volume of the chamber with the breakage, through decompression, of the ropes of extruded paste.
